Move all system prompts outside the repository for security

[tanweersalah]

Description:
Currently, our system prompts (security, guardrails, and other sensitive configurations) are stored directly in this repository. Since the repo is public, this exposes potentially sensitive information that could be misused or give insights into our internal security measures.

Problem:

• Exposes internal security/guardrail logic to the public.
• Risk of malicious actors circumventing safeguards.
• Violates best practices for handling sensitive configuration.

Proposed Solution:

• Move all system prompts and guardrail configurations outside the repo.
• Store them securely in a private configuration store (e.g., environment variables, private config repo, or secrets manager).
• Reference them dynamically at runtime, rather than embedding them in source code.
